Hi people, I installed Dayz in my external HDD as I usually play it on my laptop and didnt want to have the installation files on there for the few times I play. I now installed Dayz commander on my desktop, plugged in my external HDD and told commander where the install files are. All works fine But when I launch the game I get the Bad serial on setup error as if my key was stolen or whatever the reasons are that the other people get it. However if I then plug the HDD in my laptop again I can play normally. Is there a way to fix this?? Do i have to copy all the profile files etc? thank you very much :)
